Help!

[AshleyOconnor]

Ok hello allow me to introduce myself .. My name is Ashley Oconnor i have purchased NTL back in 2005 - 2006 i've had no problems what so ever with it until the past 3-4 days.

Basically every 5-10 Minutes the internet would disconnect forcing me to take out the power cable and place it back in for the connection to reset, Sometimes it would just reset by itself, Also sometimes it just disconnects for about 5 seconds and fixes itself, Unfortunatly this is rarely the case.

The 'Send' light on my modem keeps flashing when i do get disconnected and the other day my 'Ready' light was flashing but for now its just the 'Send' light.

Below are the logs from my latest Disconnect.

Please help me
Ashley

What BB service are you on and what modem are you using.

If you are using a router try connecting direct to eliminate the router from the equation.

Can you open your browser with http://root:root@192.168.100.1 click on 'login'
Now let us know what it says the values for:-

Downstream Modulation
Downstream SNR
Downstream Receive Power Level

Upstream transmit Power Level

Maximum Downstream Data Rate
Maximum Upstream Data Rate

[AshleyOconnor]

Hello, Thank you for responding to this thread.

i am on a NTL Cable Modem: 250
Model Number: E08C007
2MB Broadband
Downstream Modulation: QAM256
Downstream SNR: 41.5 dB
Downstream Receive Power Level: 5.2 dBmV

Upstream transmit Power Level: 49.0 dBmV

[Mick Fisher]

Hmmm your downstream recieve power level might be considered borderline but overall that looks pretty good.

You don't say whether you use a router?

Have you checked that all connections from the wall box (isolator) to your computer are good?

[AshleyOconnor]

I do use a router however at the moment its plugged directly as i was wondering earlier whether it would fix it direct, Obviously not, And i have checked the cable yes however could that be the problem? A cable with say an indent in it or something? Say like a door kept shutting on it and the cable gets squeezed together and bent if you get me.

But surely that would stop the whole connection permanently and not in small 5 minute disconnects

Cables that have been continually bent or in one place have been known to fail with similar results when repositioned or bent another way.

Look at replacing your Ethernet cables first, Cat5E patch cable.

Your logs are actually quite normal, because when a modem is rebooted it receives every single update that was ever issued for that modem required or not.

Check my own logs, I even have logs with the year 1970 in them!.

And my modem is working fine.

If it's coax that we are talking about, the conductor is a solid copper strand and is not intended to flex. It's quite likely that it is now broken inside the insulation.

It definately sounds a likely suspect and needs eliminating by replacing with a new cable.

You will probably need a VM engineer out to do it.

I am talking about the Ethernet cable not the Coax, it has been in other forums and an article online, cannot remember exactly but I have read it.

[AshleyOconnor]

Hello, I would like to bring your attention back to this thread, I have recently had another modem installed by VM, And i still get the same issue, Its only been happening for the past few days however, I find this highly annoying and may end up leaving VirginMedia for good.

[r00t]

Direct connection?
Tried a new patch cable?
What happens to the lights on your modem when your connection drops?

[AshleyOconnor]

Im running though a router also, However the same problem happens when i connect direct, I don't think its a patch cable because of the fact, When the connection drops the other computers such as Xbox, 2 Laptops also drop. And when the connection does drop usually the Send light flashes about once per second and i THINK the ENET flashes.

Please help me this is really annoying me

[Axegrinder]

The ENET light flashing is a good sign, means there activity between the modem and pc/router.

[ceedee]

Loads of questions I'm afraid, Ashley... but I'm sure we'll find some answers soon.

Which router are you using?
Did you mean that you didn't experience the same repeated connection drops for a while after installing the new modem?
Which UBR are you connecting to? (Click on "Connection" near the top of this page but delete out your IP number)
Could you copy across your current modem power level (as you did in post 3 above)?

[AshleyOconnor]

Sure thing, Also the recieve light flashes not the send my mistake,

I am using netgear WGR164 router,
cpc1-hatf4-0-0-cust972.lutn.cable.ntl.com would be the UBR and

Downstream SNR: 40.8 dB
Downstream Receive Power Level : 3.3 dBmV
Upstream transmit Power Level : 59.5 dBmV
Downstream Modulation : QAM256

that upstream power seems to be too high - you will need a tech visit to sort that out, it cannot be done remotely.
